forensic science Articles

Forensics and hydrology are two terms that may not seem to go together well. To the uninitiated, this combination may evoke images of the crime scene investigation that ensues when some patsy goes into the drink wearing cement overshoes. Rather, the term environmental forensics, essentially the parent discipline of forensic hydrology, has found its way into contemporary parlance owing to ...

Automotive forensic examination is the systematical analyses of failed automotive components in the pursuit of and the identification of the cause(s) or root cause(s) of the physical damage or other disablement done to vehicle by collision. It comprises a combination of science, experience and some art by using the laws of physics, mathematics, engineering, etc. mixed with the expert's real–world ...

When a site is contaminated with petroleum products, there are many questions. How did it happen? When did it happen? And, most importantly, who is responsible for paying to clean it up? This fall, Rutgers University’s Office of Continuing Professional Education (OCPE) will ...

This paper will focus discussion on the building envelope, the science behind the inspection, techniques for inspection, and verification of the findings. Because much of our work is pioneering, we will end by addressing the question 'Where do we go from here?' WHY USE INFRAREDA picture says a thousand words; infrared thermography is the only diagnostic technology that lets you instantly ...

The Raman technique is gaining widespread acceptance as an investigative tool for forensic applications. This article focuses on the use of portable and handheld Raman spectroscopy in the field of forensic science and illustrates it with real-world examples. The benefits of Raman spectroscopy are well recognized for the molecular identification of unknown molecular compounds and as a result the ...

Forensic laboratories working with hard samples such as hair [1, 2J, bone [3], teeth, skin, etc. experience difficulties with DNA extraction due to the high energy needed to grind these tissues. Moreover, biological evidence is available in small quantities and the current techniques used do not provide high quality results. The Precellys homogenizers provides high speed sample disruption based ...

Computer forensics forms a vital part in the procurement for better data security. It helps law enforcement officers as well as computer forensic specialists to unveil the illegal dealings of miscreants who usually cover up their cyber crime in the foggy environment of the digital world. Computer forensics makes it easier for law enforcement officers to ferret out cyber miscreants and convict ...

Research Objectives To validate SERS in a forensic context, and show the conditions under which Raman spectroscopy and especially SERS contribute to the value of forensic science. To compare both SERS and normal Raman spectra, and to explore the conditions in which each may be of value. To validate certain specialized SERS techniques To provide useful ...

Abstract The objective of this presentation is to discuss the results of the evaluation studies conducted on four commercially available field-portable Raman spectrometers. The data presented in this comparison will affect the forensic science community by assisting a prospective user in determining which portable Raman device may best suit their agency’s needs. This presentation ...

The determination of measurement uncertainty is a critical issue in all fields of experimental science; its importance becomes maximal in the specific case of forensic analytical chemistry (including doping analysis), where uncertainty has not only to be calculated with precision, but it also has to be both small and reliable enough to support effective decision making. This contribution gives a ...

This morning the U.S. Fish and Wildlife Service held an “ivory crush” event in Times Square in New York City, highlighting the huge problem that is elephant poaching and wildlife crime more generally. In addition to raising awareness of the problem, the point of pulverizing 1 ton of seized elephant tusks is to diminish demand and disrupt the ...

Forensic investigations are often a combination of both scientific techniques and historical background studies. One example that is often used is the background to leaded gasoline. Gasoline service stations can be found on many street corners and, in fact, there were many more service stations in the United States in the 1960s than there are today. This means that potential sources of ...
